MIRANDA HYDROELECTRIC POWER PLANT, PORTUGAL
The Miranda Dam is located on the Douro River, within the Douro Internacional Natural Park in the northeast of Portugal, on the border with Spain.
Constructed between 1955 and 1961, it is a concrete buttress dam with a maximum height of 80 m, a crest length of 263 m, a crest altitude of 535 m, and a volume of 240,000 m³.
The works carried out for the construction of the plant included preliminary works, the barrier dam, intake structures, the underground power station and associated works, the control center, and the outdoor substation.
The hydroelectric power station, a run-of-the-river type, became operational in 1960 with an installed capacity of 150,000 KW and an estimated annual production of 800 GWh. Today, the plant has an average annual production of 897.8 GWh.
